SHOE POSITIONING MEANS Original Filed July 10. 1922 ber 22 and the partswhich are carried therel y rearward movement relatively to the standard16, or to permit .them to be swung forwardly by the action of a springplunger 56 which is mounted in the collar'l) and engages a portion ofthe standard 16'. As hereinafter described, the standard 16, afterbeingl swung rearwardly to'torce tne shoe againstV the heel band, islocked invariably in the same operative position, and the meansdescribedfor adjusting the member 22 relatively to the standard accordinglyserves to determine the lengthwise position of the shoe 'in Voperativerelation to both the heel band and the wipers.

rllhe shoe support is intended to be swung rearwardly by the operatorbefore the machine is started, and the'machine is provided with meanswhich operates automatically in response to such rearward movement ofthe shoe support tolock the support in operative posit-ion. For thispurpose there is mounted in bearings in the base a rock shaft 58 uponwhich is secured a loclring member or lever 60 havinga hook-shaped frontend to engage a roll 62 on the standard 16. At its rearend the lever 60is provided with a tooth 64 arranged to be engaged by a latch member 66on the lower end of a rod 68 to hold the lever initially vin idleposition with its hookshaped end upraised, as illustrated in thedrawing. The rod 68 is plvoted at lts upper end vto one arm ota'bell-.crank lever 7 0, and is connected to a spring 72 which tends topull the rod upwardly and also to hold it 'torwardlyin position for itslatch 66 to engage the tooth 64. On the lower end 'of the latch 66 is alinger 7 4 in position to be engaged by the rear end of a rod 76 whichis pivota l-ly connected at its front endjto the standard 16 and isarranged to slide through a bearing formed in a bracket member 76, therod 76 having thereon a nut S() for engaoinfr the member' 78y to limit`the forward movement of the shoe support. "When the shoe support isswung rearwardly by the operator, the rod 7 6 pushes the latch' 66 outofengagement with the tooth 64: soon as the roll 62' passes to therearet the hooloshaped end ot the lever 60, and the f lever is thereuponswung into locking position g 82 which encircles the roch b y a torsionsprin shaft 58. y Y the lever, there is provided an abutment Sil on thebase 2 which is engaged by a pad 66 on the lever.

The bell-crank is controlled by a cam 88 on the cam shaft 10, and in thecourse ot the cycle ot operations of the machine the cam permits thespring 72 to raise Vthe rod 68 until its latch 66 again connectswith thetooth 64.. y

Nearthe end ofthe cycle the cam thereafter imparts downward movement tothe vlatch and thereby swings the lever 6G toits idle position torelease the shoe support.

Y The means thus provided for locking the shoe support m operativeposition priorto the To limit the swinging movement et tennis shoes, inthe manufact-ure o1" which Y neither theupper nor the insole isvfastened to the last, since it enables the operator- 'to'position theinsole in proper relationl to the last and to the heel end ot the upperatter the upper has been clamped to the last bythe heel band. y ln theuse ofi the machine the operator mounts the lastwith its upper upon theshoe support, and alter positioning VVche heel end portion oit the upperwi'V n` its margin projecting the proper distance above the heel seatface ot `the last, and while holding the upper in proper position,swings the siee support rearwardly to force the shoe against the heelband, which wraps itself about the heel end depresses` the treadle andstarts themachine. The la:- ing operations ot the n'rachine are thenperformed in the manner described in the copending application, afterwhich tho shoe supportv is released by the action oil the cam 66, in themanner herelnbefore eX- plain ed, to permit it to swing forwardly intoposition for the operator conveniently to remove the shoe.
